Everything you need to know about Water Efficiency Calculations…

What are water efficiency calculations?

Water efficiency calculations help you understand how efficiently you’re using water in your household. They determine the water usage for new buildings and conversions demonstrating compliance with part G of the building regulations.

Why are water efficiency calculations needed

Water usage calculations are crucial for several reasons:

1.      Regulatory Compliance:

Building regulations in the UK require compliance with water efficiency standards. Calculations demonstrate that your new dwelling meets these requirements, ensuring compliance with part G of the building regulations.

2.      Resource Conservation:

Efficient water use reduces strain on local water supplies and ecosystems. By optimising water consumption, you contribute to sustainability and environmental protection.

3.      Cost Savings:

Implementing water-efficient measures can significantly reduce utility bills. Calculations help identify areas where improvements can lead to long-term savings.

4.      Health and Well-being:

Proper water management affects occupants’ health and comfort. Calculations guide decisions on fixtures, appliances, and systems that impact daily life.

The water efficiency calculation Process

Before we begin calculations, we start by asking you a few key questions and asking you to provide us with information, including product data for sanitaryware and appliances included in your project. With an accurate set information provided, we can test your design for water efficiency. You should expect to receive your report within the times quoted. Occasionally, the challenges of your project are especially demanding, in which case we will contact you directly to advise you when you should expect your report.

When do I need water efficiency calculations?

To offer most value to your project we advise engaging us for water efficiency calculations as early as practically possible. That way can help you make informed choices to achieve compliance. We are often instructed during RIBA stage 2-4 prior to a building control application being made.

What do I get?

Once you provide us with detailed information on your project we will prepare and provide you with:

•  Water Efficiency calculations

• A summary report of findings and recommendations
